(CNN) - Todd Stiefel is far from a household name, and the odds he gets recognized on a street corner, even in his hometown of Raleigh, North Carolina, are small.

For Stiefel, a slim, scruffy ex-Catholic, his public persona is his wallet and activism. Through the Stiefel Freethought Foundation, the 38-year-old has made an indelible impact on the nation’s fastest-growing “religious” group: the nonbelievers. Most of the highest-profile atheists campaigns –- flashy billboards in high-traffic areas, news-making efforts to get atheists to come out of the closet, and boisterous rallies - are funded by his fortune.

Stiefel isn’t shy about his far-reaching goals.

“What I am trying to accomplish is multifold, he told CNN. “I consider myself working on the next civil equality movement, just like women’s rights, LGBT rights and African-American Civil Rights. We are still in the early stages of eliminating discrimination against atheists and humanists. That is something I really want to accomplish.”

So far, Stiefel has pumped $3.5 million into those aspirations, and his money benefits a number of atheist organizations, from the Clergy Project, a group that helps atheist and doubting clergy out of the closet, to American Atheists, arguably the most in-your-face atheist group in the country.

Castel Gandolfo (CNN)–Pope Francis is having lunch Saturday with his predecessor, Pope Emeritus Benedict XVI, in what may be an encounter unprecedented in Church history.

Since a new pope usually takes the reins only following the death of his predecessor, this is a rare occurrence.

Francis, who was inaugurated as the new head of the world's 1.2 billion Catholics on Tuesday, has made some changes since taking the helm - most notably by adopting a simpler, personal style and calling for the Church to focus on serving the poor and needy.

The new pontiff was flown to Castel Gandolfo by helicopter for the lunch date.

(CNN) - In religious studies courses, professors often try to get their students to see the world through Hindu eyes or to walk a few miles in the shoes of a Confucian. Anthropologists refer to this as cultivating an emic (or insider) perspective. The less fancy name for it is empathy.

Barack Obama is, for better or worse, an empathetic man who has tried for years to see the world through Republican eyes even as he has pleaded for Republicans to walk a few miles in Democratic shoes. As a former community organizer, he knows that you need a little empathy all around to get anything done among people with different world views. Alas, his efforts have met with little success in gridlocked D.C.

This week, Obama took his toolbox of hope, change, trust and empathy to Israel. Addressing a group of Israeli students in Jerusalem on Thursday, he spoke of Iran and of America’s unwavering support for Israel. He even fended off a heckler, joking, “We actually arranged for that, because it made me feel at home.”
